Anthurium plant named `Leny`

ABSTRACT

A distinct cultivar of Anthurium plant named `Leny`, characterized by its relatively compactness; upright and vigorous growth habit; freely branching plant habit; dark green leaves that are glossy and ovate to cordate in shape; numerous flowers that are positioned above the foliage on strong and erect peduncles; shiny red spathes; and good post-production longevity.

The present invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium andreanum, and hereinafter referred to by the cultivar name `Leny`.

The new cultivar is a product of a planned breeding program conducted by the inventor in Schipluiden, The Netherlands. The new cultivar originated from a cross by the inventor between the proprietary Anthurium andreanum selection RP 3 as the female or seed parent and the proprietary Anthurium andreanum selection RP 6 as the male or pollen parent. The cultivar Leny was discovered and selected by the inventor as a plant within the progeny of the stated cross in a controlled environment in Schipluiden, The Netherlands.

Asexual propagation of the new cultivar by tissue culture at Schipluiden, The Netherlands, has shown that the unique features of this new Anthurium plant are stable and reproduced true to type in successive generations of asexual propagation.

The new Anthurium has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The following observations, measurements and comparisons describe plants grown in Schipluiden, The Netherlands, in a glass greenhouse with an average day temperature of 25C. and an average night temperature of 19C.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Leny`. These characteristics in combination distinguish `Leny` as a new and distinct cultivar:

1. Relatively compact plants that are upright and vigorous in growth habit.

2. Freely branching plant habit.

3. Dark green leaves that are glossy and ovate to cordate in shape.

4. Numerous flowers that are positioned above the foliage on strong and erect peduncles.

5. Shiny red spathes.

6. Good post-production longevity.

The new Anthurium can be compared to its seed parent cultivar, the proprietary selection RP 3. In addition to spathe color, the new cultivar is different from plants of RP 3 in the following characteristics:

1. Plants of the cultivar `Leny` have more, smaller and shinier leaves than leaves of the selection RP 3.

2. Plants of the cultivar `Leny` are more freely branching than plants of the selection RP 3.

3. The rooting habit of plants of the cultivar `Leny` is better than plants of the selection RP 3.

4. Plants of the cultivar `Leny` have a brighter red spathe color than plants of the selection RP 3.

5. Plants of the cultivar `Leny` have flatter spathes than plants of the selection RP 3.

6. Plants of the cultivar `Leny` flower earlier and have longer lasting flowers than plants of the selection RP 3.

The new Anthurium can be compared to its pollen parent cultivar, the selection RP 6. In addition to spathe color, the new cultivar is different from plants of RP 6 in the following characteristics:

1. Plants of the cultivar `Leny` have smaller leaves than plants of the selection RP 6.

2. Plants of the cultivar `Leny` have brighter green leaves than plants of the selection RP 6.

3. The rooting habit of plants of the cultivar `Leny` is better than plants of the selection RP 6.

4. Plants of the cultivar `Leny` have larger flowers than plants of the selection RP 6.

The new Anthurium is similar to the cultivar `Laura` (U.S. Plant Pat. filed concurrently with this application). The new Anthurium differs from the cultivar `Laura` in the following characteristics:

1. Plants of the cultivar `Leny` are more compact than plants of the cultivar `Laura`.

2. Plants of the cultivar `Leny` are more freely branching than plants of the cultivar `Laura`.

3. Plants of the cultivar `Leny` have shorter leaves than plants of the cultivar `Laura`.

4. Plants of the cultivar `Leny` have shorter and narrower spathes and shorter spadices than plants of the cultivar `Laura`.

5. Plants of the cultivar `Leny` have spadices with a yellow apex whereas plants of the cultivar `Laura` have spadices with a pink apex.

6. Plants of the cultivar `Leny` have shorter peduncles than plants of the cultivar `Laura`.

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.
